Sclerotherapy is a spider vein removal technique that uses a chemical injection, such as a saline or a detergent solution to close off small spider veins. The chemical is injected into the veins using a very tiny needle causing the spider veins to “spasm” or close up.
Other veins then take over its work. Sclerotherapy is the most popular method of spider vein removal for good reason. Sclerotherapy is considered the “gold standard” in spider vein removal and is more effective and less expensive than lasers (for spider veins, not varicose veins).
In many cases, spider veins are of a cosmetic concern only. In other cases, they may in fact be related to an underlying medical problem known as venous insufficiency or reflux (backwards flow of blood in the veins). In either situation, symptoms associated with spider veins range from itching or a dull ache to throbbing pain and bleeding.
Spider vein removal with sclerotherapy works for all skin types. Many patients say that sclerotherapy feels like a modest pinch, but areas around the backs of knees and ankles tend to be a little bit more sensitive because there are more sensory nerves in those areas.
It is important to note that your response to sclerotherapy may vary depending on factors like age, heredity, and your state of health. Spider vein removal typically takes three to six treatments, and treatment sessions are typically scheduled four to eight weeks apart.
